Regulating Size, Morphology and Dispersion of Nano-Crystallites of Hydroxyapatite by pH Value and Temperature in Microemulsion System

Abstract:

Article Preview

Nanosized hydroxyapatite (nano-HA) in narrow size distribution was prepared in the microemulsion system. The experimental factors of pH values and temperature were specially investigated in order to receive nano-HA particles with the required morphologies. Several kinds of nano-HA with different shapes, sizes and crystallization were obtained by regulating the above factors in the experiment. After the as-received nano-HA particles were heat-treated at an elevated temperature, they became a kind of globular particles with an average size of 60nm and showed excellent disperse ability in absolute alcohol.
